Tip-Variant Focal Segmental Glomerulosclerosis in a Patient With Primary Hypothyroidism: A Case Report.

Focal segmental glomerulosclerosis (FSGS) is a common cause of nephrotic syndrome (NS) and one of the leading causes of end-stage kidney disease. Endocrinological abnormalities due to the urinary loss of hormone-binding proteins, such as transient hypothyroidism, are well documented in FSGS. Secondary FSGS can arise due to viral infections, drugs, and pre-existing glomerular diseases.
